Galil / Re: A Galil Mach 3 communication problem I need help with.

So you don't fix errors and support your customers who paid for the product?

Yes, I think so. I want to be sure it gets read by the correct people, and for others to be aware of the problem. Not everyone reads all the posts on the forum, and I want others to be aware they may have a problem. I am trying to help others to solve their problems. I first reported problems in November 2014, but was not fully aware of just how bad it was. I am just becoming aware of the consequences of this, namely significant loss of position information. I think the developers did a huge service for the hobby CNC community when they developed Mach3, and want it to be the best it can be.

Never mind! I should have entered G1, not G31.

General Mach Discussion / Cannot probe in inverse time feed mode error

Mach 3 is set up and running with a Galil controller and servo motors. I can jog all three axes. However when I enter a G-code command G31 X-1 F30 I get this error and no motion. "Cannot probe in inverse time feed mode error". Any clue what that means I have done, or need to do? Everything works fine in Galil SmartTerminal.

I have had problems with Galil plugin MP3 ver 4.6. It will not allow me to config a second time, and the DROs do not seem to be related to the servo motor encoders, rather they seem only to change on motion commands from Mach3. For example, sending a MDI command of G31 X1 F30 will change the X-DRO to 1.000 even with power disconnected from the motor, and thus no encoder movement. Manually turning the motor and encoder produces no change in the DROs.

Ver 4.4 of the Galil MP3 plugin seems to work correctly.

I have a copy of ver 4.4 that I will share.

I have the same problem with ver 4.6 of the plugin, as well as a DRO issue (not reading encoders with servo motors). Smurf seems to have lost his copy of ver 4.4 which does seem to work correctly.
I have a copy of ver 4.4 that I am willing to share, and would be happy to send it to Smurf if he wants it.

Galil / Problems with Galil_ST Galil MP3 ver 4.6 plugin

I have had a lot of grief with ver 4.6 plugin. For one thing, it will not let me config the plugin a second time, Mach3 locks up due to a time out error.

Second problem, the DROs do not seem to read the motor encoders the way they are supposed to. This often leads to gross position errors. Manually moving the motors does not change the encoder under any condition I could find. The DROs only change when the motor is commanded to move from Mach3, and will change on a G31 command or a jog command even with the power disconnected from the motors and therefore no motiion. A G31 X1 F30 command will move the X encoder to 1.000 even though the motor and encoder never move! This would be normal with a stepper motor since all the DROs have to work with is the number of pulses and direction sent to the stepper.

The DP counter in Galil SmartTerminal is being incremented during manual motor moves.

Ver 4.4 seems to work correctly in both regards mentioned above. Smurf seeems to have lost all his copies of ver 4.4, but I have a copy that I am willing to send anyone who sends me a private message with their e-mail address, or you can contact me at bbutcher85@yahoo.com. I do not check my private messages very often.

Galil / Re: Gross loss of position using servos and encoders with Galil
« on: September 10, 2018, 02:14:49 PM »
I found a solution that seems to work. I am using the ver 4.4 of GalilMP3 and everything seems to work fine now. I am able to repeatedly config the plugin which would not work in ver 4.6, and the DROs now read when manually turning the motor. In ver 4.6 the DROs seemed to be getting their position value from the motor move signal in Mach3 much the same as it would with stepper motors. Manually moving the motors would not ever update the DROs, even with Mach3 reset and the High voltage turned off to the motors to allow moving them when they should be locked.
Smurf says ver 4.4 is long gone, which must mean someone destroyed it or maybe Newfangled Solutions just wants to sell Mach4?

I made a cable clamp out of aluminum angle that I attach to the computer and to the controller to hold the connector solid.

One solution, although a bit expensive is to find a DMC-185x, 186x, 187x, or 188x board. With 5 or more axes you get an additional 16 digital IO ports and I think a few more analog ports. You may need to use a separate ribbon cable connected to a second connector on the board inside the computer to access additional ports.
From the user guide: The DMC-1750 through DMC-1780 and DMC-1850 through DMC-1880 controllers provide interface
circuitry for 16 optoisolated inputs, 8 TTL inputs, 16 TTL outputs, and 8 analog inputs with 12-bit
ADC (16-bit optional).
